+checkpoint48d_pre
+o in preparation for r*:
+  new S/R (calc_grad_phi_hyd.F) to compute Hydrostatic potential gradient.
+  pass the 2 comp. of the grad. as arguments to momentum S/R.
+  but for the moment, only used if it does not change the results. 
+o add finite volume form of calc_phi_hyd for buoyancyRelation OCEANIC & OCEANICP

 checkpoint48c_post
 Modifications in treatment of initial flux forcing controls
 to avoid extra storing of flux fields.
